Abstract
The present invention provides radiation-curable ink compositions comprising pigment and a photohardenable composition; the photohardenable composition comprises a free radical addition polymerizable or crosslinkable compound and an ionic dye-reactive counter ion compound which is capable of absorbing actinic radiation and producing free radicals which initiate free radical polymerization or crosslinking of the polymerizable or crosslinkable compound.
